The precise 2D resolved data on spatio-temporal evolution of electric field are essential for understanding the uncharted dynamics of electron driven processes, such as during the formation of surface barrier discharge with coplanar electrodes configuration. The method of local E/N evaluation from the ratio of helium atomic lines intensities [S. S. Ivkovic et al, J. Phys. D: Appl. Phys. 47, 055204 (2014)] was adopted into the novel spectroscopic technique enabling fast, highly spatially resolved 2D imaging of the electric field temporal evolution. The technique was based on the employing of the ICCD camera to monitor simultaneously the discharge space via a pair of interference filters. This resulted in a synchronized, phase resolved 2D imaging of He atomic line intensities development. Achieved spatio-temporal resolution was 50 ns, resp. 25×25 μm^2 . Measurements revealed the anode/cathode directed wave fronts of high electric field peaking approx. 40 kV/cm.
